facebook graph api iphone?

I been listening around that facebook iOS sdk is not functioning properly. Is there a new iOS facebook sdk available? Please suggest if开发者_运维知识库 some one has used the facebook iOS sdk and its working fine till now. As I haven't used fb iOS sdk before, it's my first attempt. So Please do share your experience and some tutorial too.

Thanks
